Description

[Detailed Description of the Invention] The present invention relates to a loading device that receives a load from a load conveyor and delivers it to a transport vehicle such as a truck or a trolley.

When the load reaches the end of the load conveyor, the load may be disorganized due to vibrations during transfer or transfer from the sorting conveyor installed in the preceding stage, and the stopping position of the transport vehicle may be uncertain. Due to these reasons, it is not possible to properly hand it over to the transport vehicle. Furthermore, in the past, cargo was loaded one by one, and more efficient loading is desired.

The purpose of this invention is to load cargo,
To provide a device which can always reliably load two items at a time even if the stopping position of a transport vehicle is indefinite.

In order to achieve the above object, the loading device of the present invention is a loading device that receives a load from a load conveyor and delivers it to a transport vehicle, and the loading device is a loading device that receives a load from a load conveyor and delivers it to a transport vehicle. A pair of left and right moving frames movable in a direction orthogonal to the conveying direction of the conveyor, and a moving drive device interlocked with these moving frames are provided, and each moving frame is provided with a receiving conveyor that moves in the same conveying direction as the load conveyor. At the same time, a horizontal push plate is installed on the outer side, and a regulating plate located between both moving frames is arranged on the lifting platform side so as to face these horizontal pushing plates, and the regulating plate is installed side by side on both receiving conveyors. a moving operation device, a vehicle center detection device at the front end of the regulating plate, a lifting frame provided on each moving frame, and a stopper device regulating the lowering limit of the lifting frame; A free conveyor is provided between the lifting frame and the fixed part side, a free conveyor is provided on the upper part of the lifting frame, and a free conveyor is provided in the transporting direction perpendicular to the transporting direction of the receiving conveyor, and the moving frame is further provided with a free conveyor that operates in the same direction as the transporting direction of the receiving conveyor. The structure is equipped with a boosting device to do this.

According to the configuration of the present invention, the following effects can be expected. That is, by separating the moving frames from each other and slightly raising the lifting platform to adjust the receiving conveyor to the same level as the load conveyor, the two loads conveyed by the load conveyor can be separated from each other. can be received onto the moving frame by a receiving conveyor. Transport vehicles are parked before and after this, with their rear ends facing each other.
The parking position is not fixed. Therefore, by operating the moving operation device forward and backward to move the regulation plate,
This regulation plate can be opposed to the vehicle center. At this time, forward and reverse movement can be performed reliably while being confirmed by the vehicle center detection device. When the lifting platform is lowered after that, the lowering of the lifting frame is regulated by the stopper device during its descent, so the receiving conveyor becomes subordinate to the free conveyor, thereby passing the load on the receiving conveyor to the free conveyor. be able to. Next, by moving both moving frames toward each other by the moving drive device, both loads are moved toward each other in the direction of approaching each other, and are sandwiched between the horizontal pushing plate and the common regulating plate. Therefore, positioning in the left-right direction with respect to the vehicle center and correcting the load shape can be performed at the same time. Thereafter, by raising the lifting platform, the cargo whose appearance has been corrected can be received by the receiving conveyor, and the receiving conveyor can be adjusted to the same level as the loading surface of the transport vehicle. By backing up the load, the load can be loaded onto the transport vehicle. In this way, according to the present invention, the loading of cargo is

is installed. A vehicle center detection device 54 is provided at the front end of the regulation plate 17 via a support member 53. The vehicle center detection device 54 is constituted by, for example, a phototube device, and correspondingly, a detection object 55 made of, for example, a reflective tape is provided at the center of the rear surface of the truck 3. Further, below the vehicle center detection device 54, the support member 53 is provided with an elevation detection device 56 for detecting the detected object 55. As shown in FIG. 2, the receiving surface of the truck 3 is formed by free rollers 37, and is configured to be able to maintain the receiving surface at a constant level by means of a hydraulic lifter 38.
Note that the load 39 is handled via a pallet 40.

The action will be explained below. First, the truck 3 that has been stopped with its cargo platform facing the loading device 4 is lifted by the hydraulic lifter 38 and the free rollers 37
to keep the receiving surface at a certain level. In the loading device 4, the moving frames 9 are separated from each other,
Then, the elevator platform 6 is slightly raised to adjust the receiving conveyor 11 to the same level as the load conveyor 1. At this time, the elevating frame 19 is in a lowered position relative to the movable frame 9, and therefore the free conveyor 26 is lower than the receiving conveyor 11. It is also located in the middle of the boosting member 36, which is the retraction limit. In this state, the two loads 39 conveyed by the load conveyor 1 are placed on the pallet 4.
0, and are received onto the moving frame 9 by the respective receiving conveyors 11 into the state shown in FIG. At this time, the backing member 36 moves downward against the elastic force and becomes crouched under the pallet 40. Before and after this, the screw shaft 48 is rotated via the operating handle 52, and the regulating plate 17 is moved between the two receiving conveyors 1 via the swing lever 45, the connecting rod 46, and the block 18.

Due to this movement, the detected object 55 is detected by the vehicle center detection device 54, and the detection is notified to the worker operating the operating handle 52 via a buzzer, a lamp, etc. By stopping the operation, the regulation plate 17 can be opposed to the vehicle center. Next, the lifting platform 6 is lowered. Then, when it reaches a certain position, the lifting frame 19 is moved by the action of the stopper device 23.
is prevented from descending, and only the movable frame 9 is relatively lowered. As a result, the receiving conveyor 11 becomes lower than the free conveyor 26, and the receiving conveyor 11 becomes the 12th conveyor.
As shown in the figure, the pallet 40 is transferred to the free conveyor 2.
It is supported on the 6th side. Then, by operating the moving drive device 10, both moving frames 9 are moved closer to each other. During the approach movement, the elevator frame 19 also moves together,
The pallet 40 moves and comes into contact with the regulation plate 17 while the free conveyor 26 is not rotating. In this state, the moving frame 9 moves closer, causing the free conveyor 26 to rotate, and eventually the horizontal pushing plate 16 comes into contact with the pallet 40, and as shown in FIG. Positioning and correction in the left and right direction with respect to the vehicle center of No. 39 are performed at the same time. Next, the lifting platform 6 is raised. Then, only the moving frame 9 is raised in advance until the lifting plate 22 comes into contact with the lower surface of the lifting frame 19, and as a result, as shown in FIG. The pallet 40 is supported by. In this state, the moving frame 9 and the elevating frame 19 are raised together, and the receiving conveyor 11 is leveled with respect to the free rollers 37 of the truck 3. This level adjustment is easily and reliably performed by detecting the detected object 56 with the elevation detection device 56.
The receiving conveyor 11 is then actuated via the motor 14 to move the supported pallet 40 onto the track 3.
Transport to the side. Two pallets 40 are transported at the same time. Although the conveyance (carry-in) by the receiving conveyor 11 is not sufficient, the pallet 40 has already passed the pusher member 36. By activating the boosting device 28, the pallet 40 can therefore be boosted via the boosting member 36 and thus fully loaded into the truck 3.
